An interesting idea from Airsoft Innovations, this one uses a spiral system.

We’re nearly ready to release our Tornado airsoft hand grenade. It’s very combat effective spewing 180x 6mm pellets in a 3 dimensional scatter.

The Tornado uses a novel method for storing and propelling, and scattering pellets at high velocity. Twin spiral passages wrap around a machined aluminum valve body. Individually they store about 90 pellets. If they were unwrapped and straightened, each passage would measure close to 50cm. This method of storage is compact and provides a long passage to efficiently accelerate the pellet charge. You also only have to load two passages with pellets so loading is reasonably fast. Each passage opens on tangent to the valve body so when the pellets get blasted out, the reaction force causes the grenade to counter rotate in recoil. This spinning effect is augmented by two ramp features at the exit of each passage so they don’t end up scattering pellets in a flat disc. One passage traces a 45 degree cone upwards while the other traces a 35 degree cone downwards. Random bouncing against the ground when the grenade spins helps randomize the scatter even more so the distribution is quite spherical.

Be sure to check out the video, its very cool, although I question how well it functions when it doesn’t land on its bottom, unless of course it either has enough bottom weight to land correctly, or actually propels itself into a near upright position.
